The invention provides a shielding structure of a marine inverted pyramid reactor bottom and a ship, the shielding structure is arranged in a double-bottom structure below a reactor, the shielding structure is of an inverted pyramid structure, and the shielding structure comprises a shielding body and a supporting structure. The shielding structure and the primary shielding of the reactor together form complete radiation shielding containment on a reactor source item, a shielding body adopts an inverted pyramid structure form, and a'tower footing 'of the inverted pyramid structure covers a projection area of the primary shielding on a double-layer bottom; in the inverted pyramid-shaped reactor bottom shielding structure, the thickness and the material required by each step of the shielding body are determined according to a radiation shielding calculation result of the reactor; the height and material of the support structure are determined based on the structure of the shield. According to the technical scheme, complete radiation shielding can be formed for the reactor source item together with primary shielding of the reactor, leakage of the reactor source item to the surrounding area is weakened to the maximum extent, and radiation safety of personnel and equipment in the surrounding area is guaranteed.

    本发明提供一种船用倒金字塔型堆底的屏蔽结构及船舶,所述屏蔽结构设置于反应堆下方的双层底结构内,形式上为倒金字塔结构,包括:屏蔽体和支撑结构。所述屏蔽结构与反应堆一次屏蔽一起对反应堆源项构成完整的辐射屏蔽包容,屏蔽体采用倒金字塔结构形式,倒金字塔结构的“塔基”覆盖一次屏蔽在双层底的投影区域;倒金字塔型堆底屏蔽结构中,屏蔽体的各台阶所需的厚度及材料,根据反应堆的辐射屏蔽计算结果确定;支撑结构的高度及材料基于屏蔽体的结构确定。本发明技术方案,能够与反应堆一次屏蔽一起对反应堆源项构成完整的辐射屏蔽包容,最大限度地减弱反应堆源项向周边区域的泄露,保证周边区域人员、设备辐射安全。
